This high-performance Powerhead Base Gasket is engineered for Mercury 3.0-liter 2-stroke V6 outboards and built using premium-grade Victor Reinz 0.75mm AFM material. Designed to replace Mercury OEM part number 832933006, it is a precision sealing solution developed for durability, heat resistance, and mechanical stability.
 
Manufactured under controlled tolerances and used in competitive marine applications, this gasket is proven in real-world, high-output conditions where gasket failure is not an option.
 
The Victor Reinz 0.75mm composite material is composed of high-strength aramid fibers, inorganic fillers, and an elastomeric binder specifically formulated to resist fuel, oil, and long-term heat exposure. This construction provides excellent dimensional stability and sealing integrity under high-RPM conditions and wide thermal cycles.
 
Unlike standard gasket materials that can degrade under the combination of pressure and fluid exposure, Victor Reinz 0.75 AFM delivers long-term sealing performance in Mercury’s most demanding two-stroke applications. It supports a maximum sustained temperatures, making it ideal for marine engines operating in elevated thermal environments.
 
This gasket is a direct-fit replacement for multiple Mercury and aftermarket part numbers, including 832933006, 18-2739, 8329331, 8329332, 8329333, 8329334, and 8329335. It is precision die-cut to factory specifications, ensuring a consistent crush profile, leak-proof seal, and proper alignment of coolant, exhaust, and crankcase passages.
 
Compatibility spans a wide range of Mercury’s 3.0 and 3.2-liter V6 platforms. This includes 3.0L EFI engines such as the Mercury 200 (3.0L EFI), 225 EFI, and 250 EFI, which are commonly used in recreational and workboat configurations. The gasket is also suitable for high-performance direct injection engines in the Optimax and Pro XS series, including the 200 HP Pro XS, 225 HP Pro XS, 250 HP Pro XS, and the 300 Pro XS (3.2L).
 
In addition, this gasket meets the needs of high-output and racing platforms like the Mercury Racing 300X and 300XS—powerplants frequently used in offshore competition and tournament bass boats.
 
Further compatibility includes Mercury’s Direct Fuel Injection (DFI) and Diesel Spark Ignition (DSI) variants, such as the 3.0L DFI and 3.0L DSI, as well as DTS (Digital Throttle and Shift) engines like the 200 HP DTS 6 CYL (3.0L), 250 HP XS 6 CYL (3.0L), 300 HP XS 6 CYL (3.2L), and 225 HP Pro XS 6 CYL (3.0L).
 
These engines are found across a range of applications from high-speed freshwater bass boats to offshore V-bottom and catamaran hulls, where performance, durability, and consistent compression sealing are essential.
 
A powerhead base gasket in these applications must endure constant vibration, high cylinder pressure, extreme exhaust heat, and corrosive environments. The Victor Reinz 0.75 material is ideally suited for these demands, offering enhanced resistance to crush-out, delamination, and fluid leakage over time.
 
Each gasket is manufactured under high-precision conditions, ensuring flatness, edge integrity, and consistent fiber structure for reliable long-term performance. The use of Victor Reinz material reduces the risk of gasket blow-by and coolant cross-contamination, helping to maintain optimal engine temperature and compression, especially under extended wide-open-throttle conditions.
 
Engine builders, technicians, and performance specialists seeking a proven solution that aligns with OEM geometry but offers upgraded material performance will find this gasket to meet or exceed performance standards.
 
Whether used for a stock rebuild, a high-performance upgrade, or a professional marine application, this gasket delivers consistent, race-grade reliability in the heart of Mercury’s most powerful two-stroke platforms.
 
Note: Two (2) gaskets are needed if you are running the Alien Race Cowl with the sandwich plate, one (1)  on top and one (1) on bottom.
